Introduction
RVing offers unparalleled freedom to explore the open road, but it also comes with its own set of challenges. One of the most crucial considerations for any RVer is access to clean and safe drinking water. While many RV parks provide water hookups, the quality of that water can be unpredictable and often less than desirable. Concerns about sediment, chlorine, and other contaminants are valid, and relying solely on campground water without filtration can pose risks to your health and damage your RV’s plumbing system.
Fortunately, there’s a solution that puts you in control of your water quality: building a portable do-it-yourself RV water filtration system. Instead of shelling out significant money for pre-built systems, you can assemble a customized, cost-effective, and highly portable filtration unit that meets your specific needs. This article will guide you through the process of constructing your own DIY RV water filtration system, ensuring you have access to clean and refreshing water wherever your adventures take you.
Why Build a DIY Water Filtration System?
Choosing to build your own RV water filtration system offers several compelling advantages over purchasing a pre-made unit. The primary driver for many is the potential for significant cost savings. Pre-built systems, especially those with multiple stages of filtration, can be quite expensive. Building your own allows you to control costs by sourcing components individually and selecting only the filters necessary for your specific water quality concerns.
Beyond cost, a DIY approach provides unparalleled customization. Every RVer’s water needs are different. Perhaps you frequent campgrounds with notoriously hard water, or maybe you prioritize removing chlorine for a better taste. With a DIY system, you can select filter types and stages that directly address your specific challenges. You can even adjust the system over time as your needs change or as you encounter different water conditions.
Another key benefit is the ease of maintenance. Pre-built systems can sometimes be difficult to disassemble and clean. A DIY system, on the other hand, is designed with simplicity in mind. Replacing filters is straightforward, and cleaning the filter housings is a breeze, ensuring optimal performance and longevity. This ease of maintenance translates to less hassle and more time enjoying your travels.
Finally, portability is a major advantage. Many pre-built systems are bulky and cumbersome, taking up valuable storage space in your RV. A DIY system can be designed to be lightweight and compact, making it easy to transport and store when not in use. This is especially important for RVers who value minimizing weight and maximizing storage capacity.
Components and Materials Needed
Building a robust and effective RV water filtration system requires careful selection of the right components. Here’s a breakdown of the essential materials you’ll need:
- Filter Housings: These are the containers that hold the filter cartridges. You can choose between single-stage or multi-stage systems depending on the level of filtration you desire. Single-stage systems are simpler and more compact, while multi-stage systems offer more comprehensive filtration. Choose housings made from durable, food-grade plastic.
- Filters: This is where the magic happens. Different types of filters target specific contaminants. A basic system typically includes:
- Sediment Filter: This filter removes particulate matter like sand, silt, rust, and other debris. It’s the first line of defense and protects subsequent filters from clogging.
- Carbon Filter: This filter removes chlorine, odors, and improves the taste of the water. It also reduces volatile organic compounds (VOCs) and other chemical contaminants.
- Optional Filters:
- KDF Filter: This filter uses a copper-zinc alloy to remove heavy metals like lead and mercury. It also inhibits the growth of bacteria and algae.
- Specialized Filters: Depending on your specific water quality concerns, you might consider filters designed to remove specific contaminants like fluoride or arsenic.
- Hoses and Fittings: Use drinking water-safe hoses to connect your filtration system to the water source and your RV’s water inlet. Choose hoses that are the appropriate size for your fittings and ensure they are designed to withstand water pressure. Various fittings such as elbows, tees, and connectors will be needed to create the desired connections.
- Hose Clamps: These are essential for securing the hoses to the fittings and preventing leaks. Use stainless steel hose clamps for durability and corrosion resistance.
- Mounting Options (Optional): If you want to secure your filtration system in a specific location, consider using a base, clamps, or straps. This can prevent the system from moving around during travel.
- Tools Required: You’ll need basic tools like a wrench, screwdriver, and Teflon tape. Teflon tape is essential for sealing threaded connections and preventing leaks.
When purchasing these items, consider searching online retailers or your local hardware store. A comprehensive list of materials can be found there, including drinking water safe hose, filter housings, filter cartridges, hose fittings, and various other necessary components.
Step-by-Step Instructions: Building Your DIY System
Now that you have gathered your materials, it’s time to build your DIY RV water filtration system. Follow these step-by-step instructions:
- Planning and Layout: Before you start assembling anything, take some time to plan the layout of your system. Consider where you will be using it and how you will connect it to the water source and your RV. Determine the best configuration for your filter housings and hoses.
- Assembling the Filter Housings: Connect the filter housings to each other using the appropriate fittings. Be sure to use Teflon tape on all threaded connections to prevent leaks. Tighten the fittings securely, but avoid over-tightening, which can damage the housings.
- Installing the Filters: Open the filter housings and insert the filter cartridges in the correct order. Typically, the sediment filter goes first, followed by the carbon filter. Refer to the filter manufacturer’s instructions for specific installation guidance.
- Connecting the Hoses: Connect the hoses to the filter housings and the RV connections using hose clamps. Make sure the hoses are securely attached to the fittings.
- Testing for Leaks: Before using your filtration system, test it for leaks. Connect it to a water source and turn on the water. Carefully inspect all connections for any signs of leaks. If you find a leak, tighten the fittings or replace the Teflon tape.
- Mounting and Securing the System (If Applicable): If you are using a mounting base, secure the filtration system to the base. If not, consider using clamps or straps to secure the system in a safe and stable location.
Using Your DIY Water Filtration System
Using your new DIY RV water filtration system is straightforward. Follow these steps:
- Connecting to the Water Source: Connect the inlet hose of your filtration system to the water spigot at the RV park or campground.
- Flushing the System: Before using the water for drinking or cooking, flush the system to remove any debris or air bubbles. Let the water run for several minutes until it runs clear.
- Monitoring Water Quality: Periodically check the water quality. If you notice any changes in taste, odor, or appearance, it may be time to replace the filters.
- Flow Rate Considerations: Be aware that adding a filtration system can reduce water pressure. If you experience a significant drop in water pressure, consider using a larger diameter hose or a higher-flow filter.
Maintenance and Troubleshooting
Maintaining your DIY RV water filtration system is essential for optimal performance and longevity. Here are some tips:
- Filter Replacement Schedule: Replace the filters according to the manufacturer’s recommendations. The frequency of replacement will depend on the water quality and the amount of water you use. A sediment filter may need replacing more often if you are in an area with a lot of particulate matter in the water.
- Cleaning the Filter Housings: Periodically clean the filter housings to remove any sediment or debris. Use a mild soap and water solution.
- Troubleshooting Common Problems:
- Low Water Pressure: Check the filters to see if they are clogged. Replace the filters if necessary. Also, check the hoses for any kinks or obstructions.
- Leaks: Tighten the fittings or replace the Teflon tape. If the housings are cracked or damaged, replace them.
- Bad Taste: Replace the carbon filter.
- Winterizing the System: If you are storing your RV for the winter, drain the filtration system to prevent freezing. Remove the filters and store them in a dry place.
Conclusion
